Moon star calculator: your birth nakshatra
Your Moon star is the nakshatra the Moon occupied at the moment you were born. Vedic astrology reads that star from the sidereal Moon. Enter your birth date and place; add a time if you have it. Without a time we name every star the Moon visited that day.
How it works
The engine returns the sidereal Moon from NASA JPL DE440 and the Lahiri ayanamsa. We map that longitude onto the 27 nakshatras (13°20′ each) and name the pada.
A result within 0.5° of a nakshatra boundary is flagged. If you omit the birth time, we compute at local noon and use the Moon’s daily speed to see whether it changed star that day.
Place search uses Open-Meteo as you type. Nominatim is only queried when you submit. No India ranking boost. If a place has no time zone we do not compute. For the method behind all of our calculators, see how we compute.

Questions
What is a Moon star?
It is the nakshatra, one of 27 equal segments of the sidereal zodiac, that held the Moon at your birth. Each star has four padas. The Moon spends about a day in each star.
Do I need a birth time?
A time makes the star exact. Without one we compute the Moon at local noon and sweep the day using the Moon's speed. If it crossed a boundary that day, we name both stars.
What does a boundary note mean?
The Moon was within half a degree of the next or previous nakshatra. A few minutes of birth-time error can move the star.
Is this the same as my Western Moon sign?
No. Western signs are tropical. This star is sidereal. See how we compute for the difference.
